Recent Review: I called to set up an appointment, and the next day had one in the morning. The two service guys arrived on time, after my getting a call to let me know they were on the way. They were extremely courteous, and found the problem almost immediately. They also suggested some solutions to other heating problems I was having, and gave me an approximate quote. I never felt pressured, but will definitely consider some of these options in the future. I highly recommend Gross Heating!
